. ments in 1 permutation padlocks.

An object of the inventionis to construct a padlock having few parts, wherein the cas-v ing isprovided with a dial face and a plurality of arbor carrying hands adapted to be revolved upon the casing to be brought into register with certain of the characters I 011 the dials, the arbors being provided with tumblers having gates or notches, the same being normally engaged by a lug provided upon a slide which also engages in the notch in the shackle. and which,'when the said notches or gates arebrought into alinement with the said lug, will permit'of the actuation of the slide to bring the same out of contacting engagement with the shackle to permit of the. opening of the lock.

With the above and other objects in view, theimprovement resides in the construction, combination and arrangement of parts set forth in the following specification and falling within the scope of the appended claims.

may be here stated that it is primarily my.

purpose to have thetumblers arranged at the factory during the manufacture of the locks,so that each of the locks sent out from the factory will have a different combination and of course the purchaser will be informed of the proper combination. l

As illustrated in thedrawings the device is a padlock, and the outer face, indicated by the numeral 2, is provided with a central: aperture 3, while the'inner or back face t is formed with an elongated slot 5 through which passes the stem 6 ofa slidable member 7 The slidable member 7 includes a flat plate 8, and thestem 6 is secured tothe plate adjacent one of the ends of said plate, the outer end of the stem 6 being provided with a milled head 6 which contacts with the outer face of the rear plate of the lock casing, it being understood that the plate 8 is arranged upon the interior of the casing and also contacts with the inner face of the-said back plate of the said casing. The plate 8 is influenced by a spring 9that is secured in i supporting plate 22 that is secured in the 100 lock casing. The end of the leg 14 is provided with a depression within which is seated a spring 20 that exerts a tensionbetween the inner wall of the depression and i the lower wall of the casing or a lug pro- 105 vided upon the said lower wall ofthe casing to move the shackle longitudinally in an outward direction with relation to the easing. This outward movement is limited by stop members 21 provided upon the leg 14 110 which are adapted to contact with there ferred to plate 22. The longer leg 14 isprovided with a transverse notch 15 andthe spring 9 is designed to move theplate whereby to cause the lug 17 thereof to be recelved in the said notch 15 to retain the shackle in locked position. The shorter leg 19 of the shackle 13 also passes through a suitable opening 19 in the top of the casing when the shackle is in locked plosition sandwthe numeral 23 designates an angularly disposed plate arrangediin the casing below the said opening 19. This plate not only. provides a stop for limitingthe inward movement of the shackle to bring. the notch 15 ot the leg 14 thereof into alinement with. the lug 17 of the plate 8, butalso vprevents thesinsertion of an instrument through the openmg 19 to interfere with-the valinement otthe tumblers in.- the lock, which will hereinafter bereferred to in detail. The outer face of the casing has impressed thereon a number of indicating characters,- indicated by the numeral 24, the numerical characters as therein is provided withia ,pluralityvof depressions 25, one of which being arranged radially of! eachuof the lndicatlng characters L i 24 andthesedepressions 25 are adapted one to receive a spring actuated detent 25 provided upon ill 1631111161 .face or body portion ofian indicator 26 the same being. provided with ahand, 27.. Thelhand, adjacent its infdicatingao r pointer portion is provided with anoutwardly extending lugo'r finger piece 28, and the said body iscentrally provided with anfiarbon 29 which. passes through the opening 3ninthe plate 2 of the .lockmThe:

arbor 29 comprises a hollow tubular member anolhas secured thereon a disk31, the said disk, having; ahperipheral notch 32; Arerangedwupon-the arbor 29abetween the notched disk. 31uand the outer face 2 is a a pressure spring 33 which is adapted to'bring.

itaPassingithrough-:the hollow arbor 29 of the indicator member 26 is the rounded portion of the stem or-arbor d3-for an indicat ing finger 44-,ithe last mentioned finger being disposed over and rotatable upon'thebody of the indicator 26; Theindicating point or member of the last mentioned "-finger is adapted to contact withfthe ofi'set finger member 28 ofthe member 27, to limit the rotary movement a of the last mentioned finger upon themen'1ber26, and this finger isadapted to be brought intoyregister with certain of the indicating marks 24 upon the face2 of the casing toireach thepropercom bination as will presentlybe described. The innenend of the arborv 4-3 is square to receive the square bore of a disk 47, the said disk having a peripheral notch 48 corresponding with the notch 35in tl1e:disk-=3 l and having an opening 50 to receive the finger 36 of the said disk 34:. Thus it will be noted that the disks 34: and 47 are connected and are adapted to be rotated in unison when theindicating member-d4 is rotated upon the indicating member 26. i

-.The operation ofthe device may be briefly described-asfollows: It is, of course, understood that the operator is acquainted with the proper operation whereb y all of the notches in the disks and tumblers' w-ill 'be brought to alinewith the tongue 18 on the lug-17 of theslidable 1nember 7, whereby the said member may be Ineved to bringits lug out of engagement with the notch I 15 in the longer leg 1450f the shackle 13 to permit of the spring 20 moving the shackle out Wardly of: the lock. The member 26 is first turned to bring its finger 27 to register with one of thecharactersza24e upon the dial face so that the operator is assuredthat the notch 32 of the disk 3-1is brought opposite. the tongue 18 of the lug-17: The disks-34 and 47 have their nbtches 35 and48 alining and gage with the opposite or end wallsbf the concentric slots 42in the respective disks 37, 38 and 39. As these slots vary in lengths itwill be apparent that the operator must be well acquainted with the combination in order to manipulate the member '44 so as-to bring the notches of the said disks 37,38 and 39 into alinement with each other and into alinement with the notch 32 of the disk 31. W Vhile the disks 37, 38 and 39 are loosely arranged upon the arbor of the member 36 the frictional engagement between the said disks and the spring frame members 41-41 is such that "the disks will not freely turn unless the end walls of their slots are contacted by the finger 36 so that when one of the disks has its notch properly alining with the tongue 18 of the slid-able member and the notch 32 of the disk 31, the said disk will be retained in such position until again contacted by the finger 36. When all of the disks are brought to proper alinement with the notch 32 of the disk 31 and the tongue 18 of the slide 7 it Will be apparent that a lateral pressure imparted upon the knob 6 of the slide will cause the plate 8 to be moved laterally in the casing bringing the lug 17 out of the notch 15 of the shackle and the tongue 18 into engagement With the alining notches in the respective disks or tumblers.

Having thus described the invention, what I claim is:

1. A permutation padlock including a casing having depressions in one'of the faces thereof, a spring pressed shackle in the easing, a sliding member coacting with the shackle for securing the same in locked position in the casing, arbors in the casing one comprising a sleeve member receiving the other arbor, hands upon the exterior of the casing for both the arbors, a notched disk secured to one of the arbors, a finger upon said disk, notched tumbler members having arcuate slots of varying lengths disposed upon the said arbor and having the finger of the said disk received in the said slots, a second notched disk secured to the inner arbor and connected with the finger of the first mentioned notched disk and a spring detent upon one of the hands engaging with referred to depressions in the face of the casing.

2. A permutation padlock including a casing, a shackle having a notched leg received in the casing, spring means for normally moving the shackle to an unlocking position, a slidable member in the casing, a lug carried thereby and designed to engage in the notch of the shackle to hold the shackle in locked position, arbors, one comprising a sleeve and the other comprising a stem revolubly received in the sleeve arranged in the casing, operating members for the arbors arranged exteriorly of the casing, a notched disk sccured to the sleeve, a plurality of other notched disks loosely arranged on the sleeve, one of which being disposed adjacent the referred to fixed disks, and the remaining disks having arcuate slots of different lengths, means between the disks for normally retaining the same against movement on the sleeve, a notched disk rigidly secured to the end of the stem projecting through the sleeve, and a finger member connecting the last mentioned disk with the referred to loosely arranged disk upon the sleeve adjacent the fixed disk, and said finger passing through the arcuate slots in the remaining disks, all as and for the purpose set forth.

In testimony whereof I aflix my signature in presence of two Witnesses.

WILLIAM J. MORGAN.
